We can use onMouseOver and onClick for the same picture or text.

To accomplish this we put the onMouseOver and the onClick in the
same anchor tag.

<a onMouseOver ="document.mainpic.src = three.src"; onClick="window.location=m3.html"> <img src= "threethumb.jpg" border = 0></a>

As you mouseOver the picture we can make a picture in another part of the page change
We can also go to another page (m3.html) if we click on the picture
